The tippler, is provided with end plates fitting as closely to the contour of the loaded truck 7 as possible, and with a peripheral casing 8 leaving an opening at the top for discharge of the contents. A modified construction of this cylindrical casing is described. The receiving-hopper 9, which delivers to the screen 3, is extended at one side by a casing 1 with an inwardly projecting upper edge and at the other side is covered by the casing 21. The space between the platform 2 and the upper side of the screen is enclosed by fixed walls 10, and detachable plates 11 resting on the sides of the screen. Similar plates 11 bridge the gap between a roof 12 and the forward part of the screen. Hinged flaps 14 with flexible lower edges cover the discharge end of the screen. The hoppers 16, 17 fit closely against the lower side of the screen. A suction duct 15 is connected directly to the enclosed space above the screen and by means of pipes 18, 19 to the space below the screen. As the tippler turns clockwise from the position shown in the Figure, an increasing air space is opened up between the casing 8 and the top end of the casing 1 until the opening in the casing 8 has passed this point, and the other wall of the casing then re-closes it. From this point onwards the only air entering is through the gaps in the end walls until the tipping is completed. Means for encasing a four-way tippler also are described and illustrated.

Title: Impulse counting circuit
IPC: H03K23/82
Filed: 1942-06-12
Abstract: 555,392. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. June 12, 1942, No. 8050. Convention date, June 20, 1941. [Class 40 (iv)] An impulse-counting circuit applicable to forward impulsing but described with reference to a reverting-impulse system, comprises a number of cold-cathode discharge tubes one of which breaks down in response to each impulse and prepares the next one for operation. As shown, impulse-relay 26 in its normal position connects one side of the charging battery 30 to condensers 10-19, the other sides of which are connected to the other side of the battery through individual resistances 10<SP>1</SP>-19<SP>1</SP> and 71-79 and a potentiometer 60. The register-set 81 applies a marking voltage to the control electrode of a particular tube as at 87. When the sending operation is to begin relay 28 energizes relay 27 and connects positive battery to the main anodes of all the tubes and replaces the normal shunt round relay 26 by the fundamental circuit in which relay 26 and the line relay 20 of the selector pull up. In response to the resulting energization of the up-drive magnet, the relay 26 is intermittently short-circuited and alternately charges and discharges the condensers 10-19. The charging current increases the negative potential of the cathodes of all the tubes but this is ineffective except in the tube to which the marking voltage has been applied. As shown, the tube 4 is so marked and when the first reverting impulse arrives, it breaks down. The main discharge current passing through resistance 74 raises the potential of the control anode of the next tube after a delay period fixed by the charging time of a condenser 43. The next reverting impulse thus breaks down tube 3 and so on. The main discharge in the last tube 0 of the chain passes through relay 29 which releases 28 to open the fundamental circuit and stop the switch. 27 also is released and the register circuit changes the marking in accordance with the next digit. In a modification, Fig. 2 (not shown), the tubes have separate control cathodes which are brought to the break down potential by the discharge of a common condenser, the condenser-discharge circuit being connected to the control cathodes via individual resistances. Specification 436,420 is referred to.
